We have attached a SCSI RAID system, via an AHA3940 and during a stress test the system hangs. The stress test is seven processes running which create a large number of small files than deletes them all. The sympton is that the system locks up, no output on console and nothing logged. We have tried this on several different hardware platforms and gotten the same result. We have tried it on WindowsNT and Linux and the test appears to run okay. We have tried it on FreeBSD 4.0 & 4.1 and get the same the bug. Help ! Regards Dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
